Answer 2

Answer:

• Complex sentences.
• Third-person point of view.
• Impersonal tone.

Explanation:

These are the elements that make this text formal. By using complex sentences, the author establishes his credibility, and signals which kind of audience is intended to read this text. Moreover, the third-person point of view emphasizes the fact that the text is meant to be an objective assessment of facts. Finally, the impersonal tone takes away the focus from the author and places it on the topic.
